Installing USB Driver
To use the USB function, it is required to install the driver on the PC. Follow these steps to
install the driver:
1. Insert the software DVD. It will run automatically and pop up a window.
2. Click
Install GeoVision USB Devices Driver
. This dialog box appears.
3. Click
Install
to install the drivers. When the installation is complete, this message will
appear:
Install Successfully.
4. Click
Exit
to close the dialog box and restart the PC.
To verify the drivers are installed correctly, go to Windows
Device Manager
after restarting
the PC. Expanding the
Ports
field, you should see
Prolific USB-to-Serial Comm Port
or
XR21B1411 USB UART
depending on the version of the driver. The COM number in the
parenthesis indicates the COM port currently in use.
Note:
If you unplug the GV-NET/IO Card from the PC and connect another GV-Net/IO
Card to the same USB port, the COM port may still be changed. Access the Windows
Device Manager
again to look up the new COM port number.
